(x+1)(2x-3)+2(x+1)(3-2x)+(x+1)²(2x-3)因式分解(x+1)(2x-3)+2(x+1)(3-2x)+(x+1)²(2x-3)因式分解(x+1)(2x

(x+1)(2x-3)+2(x+1)(3-2x)+(x+1)² (2x-3) 因式分解
(x+1)(2x-3)+2(x+1)(3-2x)+(x+1)² (2x-3) 因式分解

(x+1)(2x-3)+2(x+1)(3-2x)+(x+1)² (2x-3) 因式分解
解(x+1)(2x-3)+2(x+1)(3-2x)+(x+1)² (2x-3)
=(x+1)(2x-3)-2(x+1)(2x-3)+(x+1)² (2x-3)
= -(x+1)(2x-3)+(x+1)² (2x-3)
=(x+1)² (2x-3) -(x+1)(2x-3)
=(x+1)(2x-3)[(x+1)-1]
=(x+1)(2x-3)x
=x(x+1)(2x-3)

(x+1)(2x-3)+2(x+1)(3-2x)+(x+1)² (2x-3)
=
(x+1)(2x-3)-2(x+1)(2x-3)+(x+1)² (2x-3)
=
(x+1)(2x-3)[1-2+(x+1)]
=(x+1)(2x-3)[(x+1)-1]
=X(x+1)(2x-3)

=(x+1)(2x-3)(1-2)+(x+1)(x+1)(2x-3)
=-(x+1)(2x-3)+(x+1)(x+1)(2x-3)
=(x+1)(2x-3)(-1+x+1)
=x(x+1)(2x-3)
